kresd/cache/kr_cache_peekについて、ここに記述してください。

~/kresd/lib$ grep 'kr_cache_peek' *.c

zonecut.c:      if (kr_cache_peek_rr(txn, &cached_rr, &rank, NULL, &timestamp) != 0) {
zonecut.c:      int ret = kr_cache_peek_rr(txn, &cached_rr, rank, NULL, &drift);
zonecut.c:      int ret = kr_cache_peek_rr(txn, &cached_rr, &rank, NULL, &drift);

zonecut.c 中で kr_cache_peek_rr を見ている。　

• zonecutが rrcacheを利用しているということだが、これがおかしい。
  • zonecutはRRSetとは別に管理する方がよい。
  • そして、NXDOMAIN返答などはすでに別に管理されているのだから。
